Monoecious. Dull dark green or olive. Stem slender, translucent, 

 without cortical cells or spine-cells or stipule-cells. Branchlets 

 usually 6 (more rarely 7 or 8) in a whorl, forked or more rarely 

 trifld, with acute but not mucronate 1 - celled points and rays. 

 Primary whorls always lax ; those of the secondary whorls similar 

 and more compact (when it is the form subcapitata of Braun and 

 C. nidifica of collectors, according to Babington). Nucules solitary, 

 rarely in pairs, produced at the angle between the rays of the 

 branchlets, without bracts, accompanied by a globule, which is placed 

 above them, subglobular-ovoid, 7- or 8-striate (" 8- or 9-striate," 

 Groves), with a minute deciduous crown. In ponds and pools and 

 ditches, rare.

* [The title-page of this volume runs tbus : — " Kongl. Vetenskaps-Akademiens nya 

 Handlingar for ar, 1852. Stockholm, 1854." But Wallman's paper on Characeae was 

 presented to the Society in April 1853, and a separately paged extract of it was 

 published in 1853, therefore, although it has been thought advisable to quote the 

 volume as for 1854 (the volumes of this Journal not being numbered), the real date 

 of publication of Wallman's monograph is 1853. A French translation by 

 Dr. Nylander was published in 1854.]
